He doesn’t know. he just shrugs whenever we mention it. Or he’ll say “I don’t know, I just don’t have anything to say”. Another example is when someone scores a goal in lacrosse all the offensive players give them a high five or a fist pump. He just stands there and does nothing. When we mention it to him, he’ll do it once or twice in the next game but then go back to doing nothing. Not sure if its shyness or he’s just out to lunch.
